ELECTRIC FLASH-LIGHT.

Specification of Letters Patent.

Patented Oct. 29, 19112.

Application filed September 1, 1911. Serial No. 647,257.

To (ZZZ "whom it may concern:

Be it known that I, JOSEPH F. \Vaonnn, a citizen of the United States, residing at South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Electric Flash-Lights, of which the following is a specification.

This invention relates to electric flash lights.

One object is to provide an electric lamp particularly adapted for application to a door or door frame for the purpose of flashing a light across or near to akey hole, so that it may be readily visible when it is desired to lock or unlock a door in the dark.

Another object resides in the provision of an electric lamp which may be supplied from the same source as operates a door bell or by separate batteries for the purpose of illuminating that portion of the door in proximity to the key hole, to enable ready insertion of the key in the key hole.

\Vith the above and other objects in view,

.the present invention consists in the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and particularly pointed out in the appended claims, it being understood that changes may be made in the form, proportion, size'and minor details without departing from the spirit or sacrificing any of the advantages of the'invention.

In the drawings: Figure 1 is a face view of a door with respect to its frame, with the latter broken away to illustrate my invention applied to the frame. Fig. 2 is'a front view of my invention. Fig. 3 is a front view of the body portion of the casing. Fig. 4 is a rear view of the body portion of the casing. Fig. 5 is a view, partly in elevation and partly in section, showing my invention. Fig. 6 is a face view of the back plate member.

Referring now more particularly to the accompanying drawings the reference characters 7 and 8 indicate a door frame and door, respectively, the latter having the usual key slot 9, and the frame having inserted in the door jainb adjacent the key slot a suitable casing A inclosing an electric lamp.

My improved lamp consists preferably of a body portion 10, which may be of porcelain or any other suitable materiahprovided with a lamp chamber 11, whose interior is preferably highly glazed to serve as a reflector for the lamp, and a push button recess 12 for the reception, respectively, of the electric lamp 13 and the pushbutton 14. The body 10 has projecting portions 10* provided with bores 10 through which may be passed screws or other suitable fastenings to secure the device flush with the door jamb. A face plate 15 is secured over the front of the body portion 10 by means of screws 16 and 17, which have working fit in the nuts 18 and 19, respectively, located in suitable sockets in the projecting portions 10 of the body 10, as clearly shown in Fig. 5.

Before the facing plate 15 is positioned and the push button 14 inserted in its cham ber 12 so that, after the facing plate 15 is secured to the outer face of the body 10 by means of the screws 16 and 17, the glass 20 and the push button 14 cannot become accidentally dislodged fro-m their positions.

The character 22 indicates a back plate which is secured to the body 10 by means of elongated screw bolts -or other suitable fastenings 23 passed through the openings 24 and 25 of the body portion and openings 24 and 25 of the back plate, respectively. On this back plate 22 are mounted terminal necting the circuit of a door bell or other source of current, the lowermost of said terminal for cooperation with the spring terminal or switch 28 soldered or otherwise attached to the lamp socket 13', which latter is secured in position by the head of the uppermost bolt or binding post, the bolt and its head being suitably insulated from the socket. I

In the use of the invention it is only necessary when, in the time of darkness, it is desired to locate the key hole for the manipulator to push upon the push button 14:, which will cause the spring terminal or switch 28 to contact with the contact 27 thereby closing the circuit and causing -a flow of l ght to extend across the key hole, thus enabling the manipulator to readily find the same in order to lock or unlock the door, as Wlll' be understood.

From the foregoing it will be seen that the binding posts having its head 27 forming a posts 26 operable for the purpose of confacing plate 15, together with the body 10 and the back plate 22, both of Which latter may be formed of porcelain or any other insulating material, form a casing in which is a lamp chamber and also a recess in Which is mounted the push button for making and breaking the circuit, the formation of the body portion and back plate member being such as to completely insulate the metallic members making up the device as a Whole from each other. By highly glazing the surface of the lamp recess an efficient reflector is provided, thus obviating the necessity, otherwise, of using a separate means for that purpose.

What is claimed is 1. An electric lamp comprising a casing embodying a body portion, a facing plate, a rear plate, means for connecting the plates to the body portion, said body portion having a lamp chamber, binding posts secured to the rear plate with their inner ends form ing contact members, a lamp socket secured to therear plate by one of said binding posts and projecting into the lamp chamber, a lamp mounted in said socket, a contact member secured to the lamp socket and movable into engagement With the inner end of one of said binding posts, and means for shifting said contact member. I

2. An electric lamp comprismg a casing embodying a body portion, a facing plate, 2;

said body portion, binding posts secured to the rear plate with their inner ends forming contact members, and a contact member secured to the lamp and movable into engagement with the inner end of one of said binding posts to complete the circuit.

3. An electric lamp comprising a body portion having a lamp chamber formed therein, a facing plate, a rear plate, means for detachably securing said plates to the body portion, binding posts secured to the rear plate, a lamp socket secured to the rear plate by one of said binding posts, a contact member secured to said socket, a lamp mounted in said socket, means unconnected With said contact member for moving the same into contact With the inner end of one of said binding posts to close the circuit, whereby all current conducting parts are mounted upon and removable With the back plate.

In testimony whereof I aflix my signature in presence of two Witnesses.

JOSEPH F. WAGNER.
